Congratulations on your pregnancy -- Emily is right -- you are showing a lot of signs of a multiple pregnancy so it's not something you can rule out. However, the only way to know for sure is an u/s. Can you ask your doc to do another one soon, just to know?
What I've been told (don't know how true it is) is that during a 3rd pregnancy, women TEND to "pop" much sooner, which would explain why you are measuring so far along, even for a single pregnancy. One of my best friends is expecting her 3rd in February and measured much further along by 10 weeks than she did with the other 2 (nearly 20 weeks per measurement) -- she's a doula and said that this is normal for a 3rd pregnancy. Again, I don't know if this is really true.
Either way, I wish you a happy, healthy, and long pregnancy. Please feel free to post here anytime....
All the best,
Ilene
